Here is your proof of Nero's being Vergil's son http://i1190.photobucket.com/albums/z460/Akune/8435e5dde71190efa8930cf0cf1b9d16fdfa60b1_zps016d9c9a.jpg

Arkham is the descendent of the priestess, but this priestess was said to be a pure maiden ( a virgin). Mary matched that requirement, so Mary was sacrifficed.

The same reason why one of these days I made a translation request here with an extract of DMC4 novel proving Trish is more than a Eva's lookalike, but share traits with her.

All this information exist, but very few people are really interested in it.
